Nothing. I can't watch movies with her because she wouldn't like my taste and get bored, I can't listen to music with her because she wouldn't understand, I can't debate her because she is intellectually inferior to me, I can't imagine anything with her because her brain is riddled with bullshit and is unable to imagine or be creative, I can't sit down and have an actual conversation with her because it would turn into a fuck fest where she's trying her best to talk over me.
There is genuinely nothing else that I could do with my girlfriend other than have sex with her. Women are incapable of philosophical pandering and abstract reasoning, so no point in treating them immaterial when they are solely material beings
